When Did the First Americans Arrive?
In this video segment adapted from NOVA, recent archaeological evidence leads scientists to revise existing theories about human migrations into the Americas around the time of the last ice age.
"We Have Got a Good Friend in John Collier": A Taos Pueblo Tries to Sell the Indian New Deal
The Indian Reorganization Act of 1934, which became known as the Indian New Deal, dramatically changed the federal government's Indian policy. Although John Collier, the commissioner of Indian affairs who was responsible for the new policy, may have viewed Indians with great sympathy, not all Native Americans viewed his programs in equally positive terms. Antonio Luhan, the husband of the wealthy writer Mabel Dodge Luhan and a Taos Pueblo Indian, was a friend and supporter of John Collier. In th
"We Didn't Have Flies Until the White Man Came": A Yankton Sioux Remembers Life on the Plains in the
In the era before the U. S. Army conquered the Great Plains Indians the region's giant buffalo herds provided the primary food and clothing source for the Indians who lived there. Indeed, in 19th century America buffalo were more numerous than people. The various Lakota Sioux tribes who lived in the area that became South Dakota and Nebraska depended largely on the buffalo hunt according to Paul Picotte, a Yankton Sioux born in 1880. In this transcript of a 1968 interview with historian Joseph C
"Speak, Garvey, Speak!"A Follower Recalls a Garvey Rally
The Jamaican-born Marcus Garvey, a brilliant orator and black nationalist leader, turned his Universal Negro Improvement Association (UNIA) into the most important black organization in the United States in the early 1920s. Garvey's speeches often drew huge audiences, and stories of Garvey's stubborn resistance in the face of white hostility proliferated among his supporters. In an oral history interview, devotee Audley Moore remembered the Jamaican's defiant behavior at a rally in New Orleans c
Slumming Among the Unemployed: William Wycoff Studies Joblessness in the 1890s
Even before the 1890s depression struck with devastating force in 1893, large numbers of jobless men and women competed in tight labor markets and faced homelessness. One of the best first-hand descriptions of "what it is to look for work and fail to find it" comes from political economist Walter Wycoff's two-volume study of The Workers: An Experiment in Reality, first published in 1899. Wycoff had abandoned his studies at Princeton to seek a more concrete appreciation of social problems. His re
Making the Atlanta Compromise: Booker T. Washington Is Invited to Speak
On September 18, 1895 Booker T. Washington, the noted African-American educator who was born a slave in 1858, spoke before the Cotton States and International Exposition in Atlanta. His Atlanta Compromise address, as it came to be called, was one of the most important and influential speeches in American history. Acutely conscious of the narrow limitations whites placed on African Americans' economic aspirations, Washington stressed that blacks must accommodate white people's--and especially sou
How Much do you Weigh on Distant Planets?
Students in the middle level solar system activity will study the effects of gravity on the planets of the Solar System. They will view movies from the lunar Apollo missions, calculate their own weight on other planets, and propose what they might weigh on newly discovered planets around other stars.
Atmosphere Applet: This program lets you study how the properties of the atmosphere change with altitude. You can study the atmosphere of either the Earth or Mars. The equations used in this program are taken from the ICAO standard day model for the Earth and from some curve fits of the Martian atmosphere gathered by the Global Surveyor spacecraft. Using the airplane graphic you can select an altitude, or you can type an altitude into the input box. The program instantly outputs a selected pro
Hurricanes: the greatest storms on earth
This website, provided by NASA's Earth Observatory, describes the science behind hurricanes. Sections include hurricane formation and decay, hurricane anatomy, information regarding storm surges, hurricane climatology, a description of the Saffir-Simpson scale and NASA study missions. Users will also find a list of references regarding hurricanes and hurricane science.
Online Statistics: An Interactive Multimedia Course of Study
Online Statistics: An Interactive Multimedia Course of Study is an introductory-level statistics book. The material is presented both as a standard textbook and as a multimedia presentation. The book features interactive demonstrations and simulations, case studies, and an analysis lab.
A Text-Book of the History of Painting
The object of this series of text-books is to provide concise teachable histories of art for class-room use in schools and colleges. The limited time given to the study of art in the average educational institution has not only dictated the condensed style of the volumes, but has limited their scope of matter to the general features of art history. Archæological discussions on special subjects and æsthetic theories have been avoided. The main facts of history as settled by the best authorities
Collaborative Work During Interventional Radiological Procedures Based on a Multicast Satellite-Terr
Collaboration is a key requirement in several contemporary interventional radiology procedures (IRPs). This work proposes a multicast hybrid satellite system capable of supporting advanced IRP collaboration, and evaluates its feasibility and applicability. Following a detailed IRP requirements study, we have developed a system which supports IRP collaboration through the employment of a hybrid satellite-terrestrial network, a prototype multicast version of wavelet based interactive communication
Graphical Representation of Geologic Time
This spiral graph visualization, which includes both marine and terrestrial components, represents 4.5 billion years of geologic time. Stratigraphy, paleontology, and geochronology study results provide evidence in support of this old earth. This graphical representation is from an article called Age of the Earth.
Radioactive Decay and Absolute Age Determinations
This site provides access to a number of visual resources and supporting material illustrating the concept of radioactive decay and its central role in radiometric dating. Visualizations include diagrams, graphs, static illustrations and photos. Resources found on this site are suitable for use in lectures and classes and may also be used as the basis for labs or other activities.
Tonto National Monument: Saving a National Treasure
tells the story of the Salado people, who thrived in the Arizona valley where Tonto Creek joins the Salt River (1050-1450 AD). The Salado culture combined customs of several American Indian groups. They channeled the river to create farmland in the desert. They built Pueblo-style buildings. They left no written records. This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.
The aim of this lesson is to enable students to be aware of how to manage their approach to studying to reduce stress. It is the fifth lesson in the study skills series and is intended to support adult learners who are embarking on a course of study and need to acquire skills which will help them to be successful. The lessons are designed as a package with key skills reinforced in each subsequent lesson so that a study culture is developed over time. They can be delivered sequentially or used in

This online PowerPoint presentation is dedicated to the phylum Tardigrada. It discusses distinguishing characteristics of Tardigrades (also known as water bears), their relationship to arthropods and nematodes, internal structures, life stages, cryptobiosis, research opportunities, classification, identification, habitat, distribution, ease of study in the lab, and more. Each slide contains illustrations and descriptions of the microscopic animal.
Arctic Bird Migration Monitoring Protocol
The purpose of this resource is to observe when selected bird species first arrive at your study site, and to count the numbers until few or none of these birds are seen. Students select a common and easily identifiable bird species in their region and observe when the bird species first arrives. Students use binoculars or telescopes to scan a study site and count how many they see. They continue to observe every other day until few or none of the selected species can be seen.
